OK, so it's like that: I've decided to go for OD pedal and finally ended up with three choices:
1) BOSS SD-1 2) MXR GT-OD 3) Ibanez TS-9
BOSS was too muddy (however great for boosting and overdriven amp), TS-9 was somehow too delicate, tone-coloring and way too expensive so I've decided to go for MXR GT-OD and never ever regret this decision. Built like tank, sound very natural with mids and lows emphasis and has a hell of versatility - can work as a standalone pedal on clean channel or a boost to get more gain on amp.
New costs about 90$, but i got it from a pawn shop for 20$ - deal of life :)
I was searching for a good overdrive, and found this good piece of harware. It has a good range of tone, and is simple to use. I like the color and the design. MXR is a very good brand!
